Smart engine technology (SET) attracts a great deal of attentions from researchers and engineers around the world in recent ten years. A "smart engine" utilizes modern control technologies to increase the performance of its components. The researches involve multiple disciplines including fluid mechanics, heat transfer, control, nonlinear sciences, computational dynamics, and even statistics. While ideally every engine component could be made "smart", the recent focuses are on compressor stability and control and combustion control. In this paper, recently developed ideas on compressor stability control are compared with each other. The criteria of comparison include not only the performance improvement but also the affordability, reliability and supportability, all of which are very important from an implementation point of view. The projects for future research are suggested as the comparisons are concluded. Since SET is still under development and many ideas are subject to the test of time, it is in some sense too premature to be reviewed or surveyed. With this in mind, this article is not trying to cover the whole spectrum of this rich research mix. Instead, the comparisons and suggestions are made to draw some useful outlines of current progresses and highlight the important areas that need more resolution. The author is in hope that the information in this article can benefit China in starting systematic SET researches for its power industry.
